In one example of my invention, the same comprises the use of a structure consisting of a plurality of sectional side pieces or ribs l forming a laminated structure which may either be made in cylindrical construction or of rectangular or other conformation as indicated by the numeral l0 in the latter case. vThe structure preferablyI has a bot# tom portion denoted respetivelyby the 11uand' having centrally `'disposed communicant" 'recesses andy boltssothatth'e bottom 2i`or2 shall befI rigidly attached *to thesuperposed n u .or-iside pieces, which twfformanotherpair," are' similarly ,tiedtogether` andgfthe vsaine plan of construction is preferablyH-followed" until theV topofthe'lvessel has beeny reached;

Myvinvention may, manifestly, be

utilized in connection With flat layers or lamlnations of various materials. ce Theorices atl the upper and lower faces of the'structure may be lilled with sealing erably have heads 32 `formed with fins 33 in` order to prevent rotation thereof.` The said bolts are preferably inserted in bores made in the superposed Wooden strips and; being slightlyA less -in'diameter thanrthat of the bolts, and the shank offeachof the latter is driven through the said bore,v after Which van internally threaded toolv 5 may be placed on` the said shank, whereupony by rotating the too'l by its handles 5', the hea-d lot the bolt Will be drawn up into the Wood.

p The -slottednut 3 may now be set on the end ofthe shank and'dravvn down by the tool 6 having means to engage the said slot,

which .tool may be turned'by-fmeans of a vvrench7 to force the nut down as far as possible. n v It is obvious that my composite structure may.. beutilized in theimanufacture of other articles .than containing vessels, as' for 'eX- ample, in any structure comprising' superposed l'ayers or sections of strips or slabs Whether made of ivovod, or metal, -or other- Wise-as. the invention resides principally in the `formation oi laminated material rigidly held together so as to constitute a solid mass.

I Wish it to be understood that I do not desire to be limited to the particular use or the'eXact details of constructionshovvn and described, for obvious modifications Will occur to persons skilled in the art.
